Jolywood JW Pro series - high-performance modules with bifacial TOPCon technology


The JW Pro series combines state-of-the-art n-type bifacial TOPCon technology with a highly efficient dual-glass construction for maximum energy yields. With outputs of up to 590 W and an efficiency of up to 22.84 %, these solar modules offer outstanding performance for commercial and industrial photovoltaic systems.

Thanks to the bifacial cell technology, they can generate up to 30 % additional power on the rear side, which significantly increases the overall energy yield. At the same time, low degradation, a low temperature coefficient (-0.30 %/°C) and high resistance to extreme weather conditions ensure long-term stable and reliable electricity production.

Why the JW Pro series?

  • High output - modules with 565 W to 590 W and up to 22.84 % efficiency
  • Bifacial technology - additional energy yield due to up to 30 % higher rear side output
  • Low degradation - 1% in the first year, then only 0.4% per year for a long service life
  • Optimum temperature resistance - Low temperature coefficient of -0.30 %/°C for higher yields at high temperatures
  • High mechanical load capacity - Tested up to 5400 Pa snow load and 2400 Pa wind load
  • Excellent low-light performance - Efficient energy generation even with low solar radiation
  • Dual glass structure - Increased durability and protection against environmental influences
